NOTE: To get a good perspective on the possible combinations, review all
configurations. These are presented as just a few that are possible.

T-238: Example Option 1

In this configuration, the EMP sensor and
rain gauge interface is installed on the outside
sensor/interface board, the X1W-2. If you construct the rain gauge heater,
note that a power cable will be required in addition to the 1-Wire cable.
Note that the EMP sensor and rain gauge must be on the same board. They cannot
be separated.
